Application led December 26, 1914. Serial No. 879,111.

To all 'whom t may concern.'

Be it known that I, OTIsL. DAVIS, a citizen o-f the United States,residing at Iowa City, in the county of Johnson and State of Iowa, haveinvented a new and useful Improvement in Stock'IVater-Tanks; and I dohereby declare the following', when taken in connection with theaccompanying drawings and the characters of reference marked thereon, tobe a full, clear, and exact description of the same, and which saiddrawings constitute part of this application, and represent, iny Figure1 a top or plan View of a stock water-tank constructed in accordancevwith my invention. Fig. 2 a vertical sectional lview of the same. Fig. 3a broken sectional view illustrating a modified form of heater.

This invention relates to an improvement These tanks are usuallysupplied with running water, but in freezing weather the water freezesso that the tanks are useless.

The object of this invention is to provide a heater. which is locatedwithin the tank below the water line by which the temperature of thewater may be maintained above the freezing point; also to provide meansfor keeping the liquid fuel submerged so vas to see that this ismaintained at a temperature above freezing point; and the inventionConsists in the construction hereinafter described and particularlyrecited in the claim.

In carrying out my invention I employ a tank 2 of the requireddimensions. Usually these tanks arel supplied by an inlet pipe 3 throughwhich water flows into the tank, and'at the desired point an overflowpipe 4 is provided which maintains the water at the desired level. Theheater employed may be of any desired form as myl invention is notlimited to the details of construction.v For illustration I have showntwo burners 5 and 6 fed by a supply pipe 7 which is preferably connectedby a flexible tube 8 with a reservoir or container 9 for gasolene,kerosene or other liquid fuel. As herein shown these burners areinclosed in a metal casing 10 through which the inlet pipe 3 extends,and over the burner or burners a coil 11 may be made in the pipe 3 toincrease the heating surfaces, the form of the coils being immaterial tothis invention; that is, they may be arranged horizontally as shown vinFig. 2 of the drawings, or vertical coils as shown in Fig. 3 of thedrawings. This casing has an upwardly extending' flue 12 extending abovethe top of the tank and the upper end being protected by a hood 13. ThisHue provides bearings for levers 14 which extend from operating handles15 downward into connection-with valve stems 16 by which the burners maybe regulated. Naturally more or less condensation will form in theinterior of the burner casing, and to provide for draining, an opening17 will be provided in the bottom of the casing which may be inclined,if necessary; and connected with this opening is a discharge pipe 18which may lead to one side of the casing as shown in Fig. 2 of thedrawings, or through the bottom thereof as shown in Fig. 3 of thedrawings. The font or reservoir 9 is preferably maintained-in positionbelow the water level by connecting to it. a weight 19, and thereservoir or font may be provided with an upwardly extending lillingneck 20. e

In freezing weather the font 9 is filled v with liquid` fuel and theburners lighted. These burners will heat lthe water as it passes throughthe burner casing, so that as it is discharged into the tank thetemperature will be well above freezing point. The water in the tank isalso kept warm by the hea-t of the casing and this warm water will keepthe liquid fuel in temperature well above the freezing point so thatcombustion at the burners is improved. A further advantage of having thefuel font or reservoir submerged is that if the water tank is located ina'barn or other building danger of re from vthe heater is very much yThe combination with a stock water-tank,

of a heater arranged therein, said heater comprising a casing having anupwardly eX- tendng flue, a burner within said easing, a feed pipeextending through said casing, a floating reservoir flexibly connectedwith said feed pipe, and means for holding the reservoir at a pointbelow the water level.

Copies of this patent may be obtained for ve cents each, by addressingIn testimony whereof, I have signed this specification n the presence oftwo subscribing witnesses.
